Abstract: A method is described for reading the data stored in a passive responder (20) by means of an interrogation device (10) including a receiving section (14). To initiate a read cycle the interrogation device (10) transmits an HF interrogation pulse which on reception in the responder (20) is used to generate a supply voltage and initiates the transmission of an HF signal coded with the stored data. The frequency of the HF interrogation pulse is varied during its transmission over a predetermined range containing the nominal frequency of the responder (20). The receiving section (14) of the interrogation device (10) includes a tuning circuit (15) which adjusts the receiving frequency of the receiving section (14) to the frequency of the HF signal transmitted by the responder (20).

Abstract: A liquid purifying device for dispensing a liquid, including a container (10, 12, 88) which has an interior space (16) for storing a mass of a liquid, and a lid member (12) for closing the interior space. The liquid is delivered out of the container, due to a pressure of a compressed air which is introduced into the interior space by air pumping means (34, 36, 52, 99). The air pumping means includes a cylinder member (36) which is reciprocated between an advanced position and a retracted position. The cylinder member is normally biased toward the advanced position, but may be held in the retracted position where appropriate. The lid member of the container has a liquid delivery path through which the liquid is delivered as desired, when a valve (66; 118, 120, 126) disposed in the path is placed in its open position upon pressing of a push-operated member (68, 112). In the liquid delivery path, there is provided a filter (72, 136) adapted to remove bacteria from the liquid delivered through the path.

Abstract: Safety closure for a water reservoir of a steam pressure coffee machine having of the top of the water reservoir (1) a rather wide hole (2) with a disk-shaped stopper (4), to which is stiffened a rod (6) that projects to the outside and that plays in a guide bush (7), which is mounted coaxially with regard to the hole (2). The stopper (4) tends to be closed, not only because of the reservoir (1) pressure, when present, but also because of a spring (12, 18, 20) that urges the rod (6) upwards, either directly or through an arm (19) or a push-button (21) which must be pressed by hand in order to open the safety closure during the filling operation. This latter being made easier by the provision of a funnel (11), that can but need not be sealed with a cover (22).

Title: Radio test loop for a radio transceiver.
Inventor: KATISKO KEIJO
IPC: H04W24/00
Filed: 1991-05-24
Abstract: The invention relates to a device for looping a radio-frequency test signal transmitted by a transmitter section in a full duplex type transceiver to a receiver section for testing the transceiver. The device of the invention comprises mixing means (23, 28) for shifting the test signal from the transmitting frequency to the receiving frequency. Interference caused in the normal reception of the receiver by the test signal is prevented by switching means (31) positioned in a device output. The switching means separate the test signal from the input of the receiver between the test intervals. The device further comprises means (D1, 35, 36, 38) for supervising the operation of the switching means (31) by monitoring the signal level in the device output.

Abstract: Un système de transmission et de décodage de données codées en biphase ajoutées à un signal vidéo, dans les intervalles de suppression de celui-ci, par exemple pour VPS, permet de sélectionner librement la position de la ligne de transmission avec une configuration fixe du décodeur, de sorte que dans le cas de VPS on peut utiliser n'importe quelle ligne, au lieu de la 16e ligne, ce qui est important lors de l'introduction du système à l'étranger. Lorsque plusieurs services de données en biphase sont transmis dans le signal de télévision, chaque service de données reçoit un code différent de démarrage. Dans le décodeur, le signal vidéo est transféré au discriminateur de niveau, qui agit comme étage séparateur de données (2), ou au dispositif (4) de contrôle du code de démarrage et au dispositif de contrôle (5) de l'anticoïncidence, montés en aval sans aucun fenêtrage de trame ni de lignes. En d'autres termes, le code de démarrage, puis les défauts de biphase de toutes les lignes de vidéotexte, ainsi que de toutes les lignes du contenu vidéo, sont contrôlés. Afin d'exclure toute possibilité de confusion, tous les 208 éléments des 13 multiplets utiles d'une ligne de données en biphase VPS servent presque de mot de synchronisation allongé, mais non rigide, qui se distingue d'une séquence aléatoire par un facteur supérieur à 1030 lors du contrôle de l'anticoïncidence biphase. A cet effet, tous les multiplets utiles ne sont admis comme étant sans défauts et transférés d'une mémoire temporaire (6) à une mémoire de sortie (8) que lorsqu'aucun défaut d'anticoïncidence n'a été détecté depuis le code de démarrage reconnu jusqu'au dernier bit utile à la fin de la ligne de données.
